WOW! You don't mention the best part of the build: it does NOT demand an expensive and hard to install sandpaper tube.I would be tempted to try the drum with the slit alone, without the pin. It would probably hold the paper fine. I had a hand sanding block that worked that way.Finally, it might run more true if the threaded rod was ground smooth in the way of the chuck.

Looks great! Your refurb was the inverse of mine; my cover was shot and the seat pan was heavily rusted. Anyone excavating down to the seat pan should consider passivating and priming the steel before replacing the foam, however.
Hee hee, there's no trick -- you actually DID IT!
I have alwasys used the fiersest pain removers, but it is very hard on my skin and the environment.
One thought: When you've done such wonderful work making the custom divider, how about leaving it to float free in the drawer. That will make cleaqning the drawer in a few years MUCH easier.
